Thanks but there is no tensioner its a small belt that goes from the camshaft around the water pump
Ok, Sorry, yes, you have to cut the belt to remove. Then replace the water pump, then install the new belt. Ford makes a special tool to do so. But you can position the new belt on the water pump pully, and the rest to the top of the camshaft pulley. Use a zip tie to secure it to the camshaft fully. Then crank the engine for half a second. The zip tie will keep it in place to go around the pulley.
